Apple's recent adjustment to encryption policies has drawn widespread attention. The new regulations may allow some iCloud data to use third-party encryption services, which, while improving cross-platform compatibility, disrupts the traditional security architecture of its closed ecosystem. This move may be a response to the pressures of the EU Digital Markets Act and reflects the dilemma of seeking balance amid intensifying competition in cloud services. It is noteworthy that the core device encryption mechanism remains unchanged, with biometric keys like fingerprint/face recognition still processed independently by the Secure Enclave. In the ongoing struggle between regulatory compliance and user privacy, Apple is attempting to carve out new pathways between data fluidity and security boundaries.
